Data Link Layer

Research by Ingrid Nelson (2010) introduced a very new and interesting method that could be used when conducting qualitative research which is the life history calendar (LHC). The article focused on giving the reader understanding of such method. Traditionally, it has been used for large-scale quantitative studies focusing on longitudinal studies, but semi-structured LHC allows participants to give their narratives and build rapport with the researcher (Nelson 2010). According to Nelson (2010),…

Large Scale Ambition While Vanguard recognizes the importance of robust analytics, none of the company’s key initiatives have been centered on analytical capabilities. Still, as a largely virtual company (retail clients are rarely given the occasion to meet with representatives face-to-face) the opportunity is obvious. However, Vanguard remains committed to meeting client needs through more traditional means like expanding call centers rather than turning certain business functions over to…

In data communication, they are always striving to increase throughput, this would include allowing nodes to transmit information over a single broadcast link without interfering with each other. To achieve this, multiple access protocols coordinate the transmission. The three classes of multiple access protocols are, random access, taking-turns and channel partitioning. With random access protocol, each node tries to randomly to use the complete broadcast link, without any regard to the other…

Self Eulogy Family and friends we have gathered here today to celebrate the life of a woman with great soul. Today marks the end of an extra-ordinary journey that began 91 years ago.

Over the past several years the popularity of Canadian data centers or also known as colocation facilities has been on the upswing. These colocation facilities located in Canada offer a number of key benefits such as; Climate, Infrastructure, Political Environment and Infrastructure. Our societies need to store and access data on the fly today has resulted in increased demand for added data center capacity and the hunt for the ideal environment to house such facilities. Toronto, Ontario - being…

Chapter Three - Conclusions 3.1 Conclusions This research aimed to verify the synthesis protocol for HPA-12 and analogues from aldehydes of Greatrex et al. (2014). Limited success in synthesising required quantities had a negative impact on the outcomes of this research, and no reasons were identified for the low yields that were obtained. Additional time, or resolution of issues resulting in low yields, would have allowed additional research and confirmation of the synthesis protocol. Long…

TLC and HPTLC Introductions Thin layer chromatography (TLC) is derived from liquid chromatography where liquid serves as mobile phase and thin layer of substance on a flat late surface serves as stationary phase. The thin layer of materials act as sorbent while the mobile phase known as solvent. Solvent will send the solutes through the sorbent depends on the strength of the mobile phase as it dissolved the solute and send them up the plate against gravity ,and resistance of sorbent…

In its beginning, the Internet was much slower than it is today, requiring companies to host their own networks in order to interconnect their computer systems. As the Internet continues to evolve and become faster with each passing year, the ability has emerged for companies to cut costs by offloading their networks to companies who host these services over the Internet. This practice has widely come to be known as Cloud Computing. The benefits of such a service are many, but it does come with…

IPv6 IPsec can be used for protection and control levels and data levels between two routers. Cisco IOS software also offers a mechanism for protecting transmitted data between two routers using a new tunnel type that uses IPv6 IPsec. IKEv1 is used to manage the key. Figure 5.3 shows the topology in which this option is used between two routers A and…
